A little over a two years ago I purchased an 02' E39. Not only was it incredible as a daily driver, but I also experienced one of the best days in my life in tracking the car at a local high-end motorsports park. Needless to say I also found how incredibly important this board was to an M owner, and through that learned a massive amount about the "misses" I made in my original purchase, what to look for in my next M car, as well as a ton of DIY help.
After selling the E39 and driving an X5 4.8is for the past year I was never satisfied. A few weeks ago I finally broke down and picked up and E60. Pics are below and its by far- the best car I have ever driven. While the new F10 has some awesome lines, I can't see parting with this for quite some time!
